The primary question we will attempt to investigate in this article is whether consciousness is a fundamental property of nature, or is it an emergent phenomenon. The nature of consciousness is shrouded in mystery. Although we understand a lot about how the world works from a third person perspective, we don’t understand the source of consciousness, even though everything we know is due to consciousness. Our conclusion is that consciousness is likely an emergent phenomenon. Consciousness emerges from physical matter (due to the arrangement of and interactions between physical matter), and ordered complexity is simply a fortunate product of random processes. We claim that defining consciousness as a fundamental property of the universe is not scientific. We also provide some evidence as to why it is likely that consciousness is emergent from physical matter.

In this article, we will also be addressing the question of whether we need fundamentally new kinds of laws to explain complex phenomena, or can extensions of the existing laws governing simpler phenomena successfully explain more complex phenomena. It is crucial to understand this question in order to obtain a better understanding of the way complexity arises from simplicity. This question is interdisciplinary in nature and would possibly have an effect on less fundamental sciences (like medical sciences), other than physics. The question involves chaos theory, emergence and many other concepts.

Gene therapy shows promise in repairing damaged brain tissue from strokes.

From the NIH Director’s Blog by Dr. Francis Collins.

It’s a race against time when someone suffers a stroke caused by a blockage of a blood vessel supplying the brain. Unless clot-busting treatment is given within a few hours after symptoms appear, vast numbers of the brain’s neurons die, often leading to paralysis or other disabilities. It would be great to have a way to replace those lost neurons. Thanks to gene therapy, some encouraging strides are now being made.

In a recent study in Molecular Therapy, researchers reported that, in their mouse and rat models of ischemic stroke, gene therapy could actually convert the brain’s support cells into new, fully functional neurons.¹ Even better, after gaining the new neurons, the animals had improved motor and memory skills.

Researchers have developed a method to recreate the formation of Lewy bodies in human neurons, shedding light on the essential roles of alpha-synuclein and immune responses in their development. This breakthrough offers new insights into Parkinson’s disease, showing that Lewy bodies form only under specific conditions and highlighting the potential…

A widely available and inexpensive antidepressant drug may soon save lives from an altogether different kind of disease.

The growth of the most aggressive and deadly brain cancer, glioblastoma, was effectively suppressed in both ex vivo human tissue samples and in living mice by an FDA approved serotonin modulator currently used to treat major depression.

It’s not a cure, but it may offer some relief and constitute an effective part of a treatment regime for glioblastoma patients. Human clinical trials are the next step; patients are cautioned against self-medicating at this stage.
